Cargo Submarines - Other Uses

Other Uses

Another (albeit black market) type of 'trade' usage is the known use of narco submarines or 'drug subs' by drug smugglers. In one case, a Colombian drug cartel was even interrupted before finishing the construction of a professional-grade, 30 m long, 200 tons carrying-capacity submarine apparently intended for the cocaine trade with the U.S. At the time of the police raid, the submarine was being constructed in segmented parts in a warehouse high in the Andes near Bogotá. However, most drug subs so far are not as sophisticated as professional merchant submarines would be, being mainly intended to run just under the surface, rather than deeply submerged.
